Pressure dependence of the photoluminescence spectra of nitrogen‐doped ZnSe: Evidence of compensating deep donors

Anthony L. Chen; W. Walukiewicz; E. E. Haller

We have measured the photoluminescence spectra of nitrogen‐doped ZnSe under hydrostatic pressure. From the pressure dependence of the peak positions of the acceptor‐bound exciton and donor‐acceptor‐pair emissions, we show that highly doped samples have two donor‐acceptor‐pair transitions, one involving shallow and one involving deep donors. Our results confirm that one mechanism limiting the free hole concentration is compensation from this deep donor.
